Selling guns is what pathetic men with Rambo fixations did in the 1980s. Whereas now it’s 2011. So you can see that having an arms fair in ExCel London today is an event worthy of your derision and disgust, and entirely inappropriate for any civilised nation, let alone the spot which is hosting the Olympics next year (Yay! World in harmony! And not at all trying to blow each other up!)
If you have the means, get yourselves down there and show your sympathy for the little old chaps with erectile dysfunction.
